Monobloc Outdoor Unit Installation Manual

10.9 Electric Heaters:

NOTE:

The installer is responsible for ensuring that the installation complies with the applicable legislation in

terms of electrical and thermal safety.

It is possible to include electric heaters in the hydraulic circuit to ensure heating in case of low OATor heat pump

failure.
When the OAT is below the Booster OAT Threshold [P604], then the booster electric heaters can be activated.

The booster electric heaters can operate at the same time as the heat pump.
When OAT is below Min OAT for heating [P514], the heat pump is stopped, and the electric heaters can be

activated.

Operation of booster and backup:

Depending on the configuration, it is possible to control up to three electric heaters or three electric heat stages

(see section 7.8.12):

•

One electric heat stage with one customized discrete output: EH1.

•

Two electric heat stages with two customized discrete outputs: EH1 and EH2.

•

Three electric heat stages with two customized discrete outputs: EH1 and EH2.

•

Three electric heat stages with three customized discrete outputs: EH1 and EH2 and EH3. This configuration

cannot be activated if DHW heater is present.

Each discrete output can control a contactor (not supplied with unit).

Characteristics

Contactor Coil:
230 VAC
50Hz

Electrical connection

Refer to Installation with booster electric heaters example

Configuration

Refer to Installation with booster electric heaters example

10.10 Boiler:

To satisfy the heating demand during periods very low ambient temperature, it is possible to install a boiler. The

boiler is considered as a backup: when it is activated, the heat pump cannot operate. Boiler is activated when OAT

is below Minimum OAT for Heating [P514] or in case of heat pump failure.

Characteristics

Contactor Coil:
230 VAC
50Hz
